I have a need to send some PLC message's from one PLC, controllogix on one network (PLC A - 172.18.239.22) to a PLC 5 on DH+ via a DH+/Ethernet bridge on another network (GW - 172.18.40.112). The is a firewall between the two networks.
Which ports are needed by the MSG instructions that need to be opened in the firewall? I have done some reading, and some things say TCP 2222 or TCP/UDP 44818. Is this all that is required? Do I set up the MSG as usual (i.e. DH+ message CIP path to the DHRIO card then DH+ node address).
